A fan delay controlling apparatus includes a connector connected to a fan of an electronic device, a power supplying module connected to the connector, and a power controlling module connected to the power supplying module. For some embodiments, the amount of capacitive coupling may be controlled after ignition of the plasma. The magnetic rotor unit includes a mechanism for changing the magnetic flux density as the number of turns of the magnet rotor unit changes. A silicon oxide inclusive layer is formed, directly or indirectly, on the reflective metallic layer. Records in this database that define the route can then be sequentially selected and the device can then display simulated progress of the car along the vectors which define the roads of the calculated route on the map image. When the calculated deviation exceeds a predetermined value, a current limit decision unit sends a limit signal to a current limiting unit.
